3mm 12mm Twist Drill Sharpener

Designed exclusively for 125 mm angle grinders, this sharpener handles twist drill bits from 3 mm to 12 mm. Its structure integrates load-bearing metal components with insulated plastic interfaces to ensure durability and operator comfort. The jig holds the bit at precise angles throughout grinding, replicating professional sharpening geometry without requiring advanced skill. It enables simultaneous sharpening of multiple bits, reducing total tool downtime. Compatible with common abrasive discs (e.g., aluminium oxide or silicon carbide), it delivers reproducible results across repeated use — whether touching up worn bits after drywall installation or restoring full cutting ability to cobalt bits used in stainless steel drilling.
